IC1805 Narrowband sent on September 01, 2015 (21:49) by Franco Sgueglia. 53 comments, 7053 views.  [editors pick]

Dopo 8 anni di fermo sono tornato a scattare. Complice la nascita del figlio di un mio caro amico che gentilmente mi ha concesso di utilizzare il suo setup . Cosa che ho fatto in questi giorni dal terrazzo di casa, a metà tra Lecco e Milano . Cielo inquinato e umido , luna piena. Come potevo provare a scrollarmi di dosso la ruggine di 8 anni di fermo? Fare una prima prova in NarrowBanding . Non è andato tutto per il verso giusto . Ma il risultato mi ha comunque soddisfatto . Sono al mio primo tentativo di elaborazione di questo tipo di foto . Siate indulgenti . IC1805 Di seguito i dati : Telescopio SW ED 80 su Skywatcher AZ Eq6, camera di ripresa ATIK 383mono , telescopio guida 80/400 acro . Dati di ripresa: Ha 3x 60 min , SII 17 x 30 min, OIII 13 x 30 min . Molte pose purtroppo le ho dovute scartare per passaggi di nuvole. No flat, no dark.

Puoi spiegare in parole semplici, se è possibile, ad un comune mortale cosa è il Narrow Banding? Grazie!

Can you explain in simple terms, if you can, to a mere mortal what is the Narrow Banding? Thank you!

Riprese a banda stretta.. H alfa,
Ossigeno terzo OIII , e in banda zolfo credo... Bel lavoretto.. :)

Shooting narrowband .. H alpha,
Third oxygen OIII, and baseband sulfur think ... Nice job .. :)

non mi ricordo di aver visto recentemente una Heart Nebula così dettagliata, soprattuto in H-alpha OIII SII come l'hai ripresa tu... vedo che gli 8 anni di assenza non ti hanno tolto lo smalto, anche se hai dovuto scartare dei frames e non applicare gli offsets quello che hai fatto è un lavoro notevole, soprattuto in elaborazione. Questa tecnica di ripresa sta cominciando a piacermi sempre di più ;-) Bellissima. Bravissimo Franco.

I do not remember seeing recently a Heart Nebula so detailed, largely in H-alpha OIII SII how you shoot you ... I see that the 8-year absence you have not removed the nail polish, even if you had to discard the frames and not to apply the offsets you've done is a remarkable work, largely in processing. This shooting technique is starting to like it more and more ;-) Beautiful. Bravissimo Franco.

Franco, bentornato allora...e con il BOTTO! MrGreen
MI ricordo ancora dei tuoi lavori e del tuo setup ai tempi del forum di astrofili.org.
Un saluto
Gp

Franco, welcome back then ... and with the BANG! -D
MI still remember of your work and in your setup at the time of the forum astrofili.org.
A greeting
Gp

Grazie a tutti !!!!!
Ciao Giampaolo ( Gp70) anche io mi ricordo molto bene di
te . Penso che ci siamo conosciuti sulla prima versione di Astrofili.org, una decina di anni fa.
Mi fa piacere incontrarti ancora .

per Pasotteo , la risposta di Canopo70 è corretta . La ripresa
narrowband ( banda stretta ) realizzata con questi filtri detti anche "interferenziali"
mette in evidenza emissioni particolari di soggetti ( quasi sempre ) nebulari :

Ha : Idrogeno Ionizzato
Oiii: Ossigeno
SII: Zolfo ionizzato

Edit:
ciascuno di questi filtri è centrato sulla lunghezza d'onda di emissione degli atomi sopra riportati :
Ha intorno a 658 nm , SII intorno a 672nm, OIII intorno a 500nm.
Un'altra caratteristica importante dei filtri e' l'ampiezza di banda . Possono essere strettissimi o più
larghi( generalmente dai 3nm a 12 nm ) . Questo significa che , centrata la banda sopra riportata,
ad esempio l'Ha a 658nm se abbiamo un filtro da 6 nm fara passare tutta la luce compresa
tra le lunghezze d'onda comprese tra 655nm ( 658-3) e 661nm(658+3) e cosi via .
La maggior parte delle nebulose hanno emissioni molto forti nella zona dell'Ha (Idrogeno) .
Per cui risulta più "facile" catturare dettagli e contrasti in questa banda . Le altre due sono un po' più
ostiche.


le riprese rispettive realizzate con questi filtri vengono sostituite , in fase di combine dei colori , ai
normali RGB . Esistono varie metodologie , una delle quali è la palette di Hubble realizzata
per le riprese fatte con HST ( hubble space telescope ) . Quest'ultima è quella che ho cercato
di applicare alla elaborazione dell'immagine che vedi .

Thank you all !!!!!
Hello Giampaolo (gp70) I also remember very well
tea . I think we met on the first version of Astrofili.org, about ten years ago.
I'm glad to meet you again.

for Pasotteo, the response of Canopo70 is correct. Shooting
narrowband (narrowband) made these filters also called "interference"
highlights emissions details of subjects (almost always) nebular:

Ha: Hydrogen Ionized
Oiii: Oxygen
SII: Sulfur ionized

Edit:
each of these filters is centered on the wavelength of emission of the atoms listed above:
It has around 658 nm, around 672nm SII, OIII around 500nm.
Another important feature of the filters and 'bandwidth. They can be narrow or more
large (generally from 3nm to 12 nm). This means that, centered above the band,
for example, if we have a 658nm filter to 6 nm gonna go all the light including
between the wavelengths ranging between 655nm (658-3) and 661nm (658 + 3) and so on.
Most nebulae have strong emission in the HA (Hydrogen).
So that it is "easier" to capture the detail and contrast in this band. The other two are a bit 'more
ostiche.


filming respective realized with these filters are replaced, in phase combine the colors, to
normal RGB. There are various methods, one of which is the palette of Hubble made
for filming made with HST (Hubble space telescope). The latter is what I tried
to apply to the processing of the image you see.

Grazie Fabio!!!

ne ho fatta una nuova elaborazione , un po' più morbida nei contrasti

Thanks Fabio !!!

I made a new drawing, a little 'softer contrasts

Lascia senza fiato...soprattutto pensando che non è stata creata da un osservatorio con attrezzature dai costi " astronomici"... Bellissima.

Breathtaking ... especially considering that it was created by an observatory with equipment costs "astronomical" ... Very nice.

" Lascia senza fiato...soprattutto pensando che non è stata creata da un osservatorio con attrezzature dai costi " astronomici"... Bellissima."

Ho pensato la stessa cosa. Immagine di grande fascino e che non ci si stanca a guardarla Eeeek!!!Eeeek!!!Eeeek!!!

Leave your breath away ... especially considering that it was created by an observatory with equipment costs "astronomical" ... Very nice.


I thought the same thing. Picture of great charm and that do not get tired looking at it wow! Wow! Wow!
